Original application flied June 15, 1911, Serial No. 633,343. Divided and this application filed October 10,

1916. Serial No. 124,921.

To all whom it may concern:

Be it known that I, LOUIS F. Dim-en, a citizen of the United States, residing at Buffulo, in the county of Erie and State of New York, have invented novel and useful methods or Processes of Rolling or Formm Cur-Wheels or other Circular Bodies, 0 which the following is a specification, accompanied by eleven sheets of drawings.

The features. of .-'my invention claimed herein are p'art of. the invention of my original application filed June 15, 1911, Se rial No. 633,343, which original-application, in accordance with the re'uirement of the Patent Oflice,"has been divi ed. The resent application isa division -froin the sai original application, end, for carrying-out my irweution, I prefer to use an apparatus or mill, such for instance, as shown and de scribed in my said original application and, the parts of such an apparatus or mill shown in the accompanying drawings are illustrative of parts of my said original application. n

The subject matterpf'the .present invention is also described .in my 'ellowed application for patent filed'June 15, 1911, Serial No. 633,343, allowed January 23, 1917 of which this application is a division, an in my co-'pending. up licstion for patent filed go 'el'No. 141,558; and it is also described or% certain features of t e,invention not herein chiimed are claimed in tlie follo'vi' copending applications filed by '!D .,w: Ap-

lication for patent filed November'- 20, 1916,

January 10, 1911 artly' described in and erial No. 132,372, and application for patent filed November 22, 1916, Serial No.

My invention relates to the manufacture of completely rolled cerwheel's, disk-wheels or other circular objects from properly. heated ingots, blooms, blanks or other wo'rk-.

pieces.

The primery object of my invention is to provide for the manufacture of car wheels andthe like in an economical, commercial,

expeditious and eflicacious manner, whereby the whole car wheel may be completely rolled and dished or not dished from a prop erly heated ingot, bloom, blank or other work-piece, including the'forming, at the op posite sides of the work-piece, of a rudimen: tax-y bore, or apart thereot, inu simple and thoroughly practicable mnuner with' the same heat and before the finished rolled dished or undished wheel, as the case may be, is removed from the apparatus or mil while at the same time securing'a uniform and maximum density and homogeneity in the metal therein which contributes meterially to the strength and durability thereof; for instance, the metal, when being rolled from theblunk or other work-piece into a car wheel or othercireular object according to my invehtion, is, especially in the tread andflange or rim portion, not ex-.

.panded radially, thereby producing incipifent cracks in the tread and flange portions o in the peripheral face ofthe rim, but 15 truly rolled'und increases ifidensity with increased :worlring, thus giving to the metal 'both'itsdue maximum strength and maximum resistance to wear. In other words, this invention of rollin produces the same efl'ect in the web portion of the wheel were not inexistence and the rim .portion rolled its total width on itsinner peripheral surface or surfaces,'as'is done on it's'outer peripheral surwheel or other circular article may be com-- pletely rolled or formed, and by which method, the time required in so producing the metal of t e rim portion as if car wheels or other circular articles is much lessened and the cost of making such wheels or other articles is enormously reduced.

Another object of my invention is to provide a. continually and automatically acting clamping process or method to revent the work-piece from becoming loose etweenits supporting means; thet 18 to say, for instan 'themetal in e properly heated work-,

piece a very soft in com arison with the metal: in its normal or co d condition and therefore has not the required resistance, which is absolutely necessary for firmly supporting the work-piece, 'hnd on which account the work-piece will become loose between or on its supportingjmeans'durinz the or positioning such rollsto any desired radial position from the center of the workpiece, all while in operation; for rolling or forming a heated circular, or approximately circular, work-piece into a car wheel or other circular body by first rolling or forming the hub and adjacent web portion and then rolling and forming the marginal or rim and the web portions to desired form, by which rolling process or steps, in whole or part, any surplus of metal in a heated Work-piece may be forced either to flow into the inner peripheral portion of the rim or into the web portion adjacent the rim portion, or into both, or forced to flow into any other portion or portions of the Wheel or other object which is to be formed from said work-piece, without leaving a raised circular portion or fin anywhere on the so finished rolled wheel or other finished object, and whereby the metal is forced to flow either to- Ward the center or hub portion or toward the peripheral or rim portion thereof, within the latter and peripheral thereto; and in which invention the work-supporting means are entirely removed from the finished wheel or other finished article before the same is removed from the ap aratus or mill; and, whereby during therol ling process the diameter of the ingot, bloom, blank or other work-piece may either be increased, decreased, or retained about the same, and, whereby may be formed the hub portion, the web portion, the rim portion, and the flange and tread of a car wheel or similar article by rolling and, during rolling also be formed into either dished or undi hed form, and whereby car wheels or other similar objects may be rolled to a true circular form of desired diameter and width and, whereby the finished car wheel or other finished object after being bored coaxial with the axis of its peripheral face and fitted or forced onto its axle or shaft, may be practically baanced.

he above-mentioned objects of my invention and others which will hereinafter appear, reduce the cost of operation in the manufacture of car wheels or other circular objects. The production of car wheels and the like is thereby greatly cheapened, the output increased and the metal, for in- .stance, in the tread and flange of the peripheral face and the whole rim portion of car wheels uniformly condensed to its maximum. thereby giving the metal in said periph eral face and rim portion its due maximum and uniform strength and its due maximum and uniform resistance to wear and thereby the said peripheral face and rim portion of the car wheel is also rolled smooth on all its surfaces to the desired form or shape without leaving a raised circular portion or fin which would have to be removed afterward by turning or other costly means.

It is, of course, understood that the various steps in the method herein described for centering or piercing and center-mg or penetrating and centering and, rollmg or orm lflg either dished or undished car wheels or other circular bodies may all be performed, in accordance with my invention, in the same apparatus or mill with one heat, or each of said steps may be effected w1th a separate heat treatment of the work-piece and separate operation. For instance The ingot, bloom, blank or other work-p1ece may be centered or pierced and centered, or penetrated and centered, and then removed from the apparatus or mill employed for carrying out my invention. After this operation the work-piece may be removed to be rolled at some future time; or, if desired, the ingot, bloom, blank or other work-piece may be rolled to a preliminary form or shape and then removed from the apparatus or mill by means of which my method is carried out and be stocked or stored for future operation or completion so that it may be later rolled, or rolled and dished to desired finished form or shape. As a further example; car wheels, disk-wheels or similar articles may be rolled to their proper form or shape and removed from the apparatus or mill and at some future time the article thus rolled may be subjected to treatment according to my methods for dishing the same, and if required they may also be rolled to true form after the dishing operation. These, however, are merely descriptive of certain steps in my method and it will be apparent that any step or operation may be completed to partly roll orv form the work-piece anddater be operated upon in the performance of any other step or steps, as may be required, but it is to be understood that all the steps of my method herein described are necessary in the manufacture of a complete car wheel or similar article.

Further objects of the invention will hereinafter appear.

My invention consists in the novel method or steps, for centering or piercing orpenetrating and centering roperly heated blanks or work pieces and completely rolling therefrom with one heat,-either dished or undished car wheels or other circular bodies before the same are removed from the appa ratus or mill, as hereinafter described and claimed.

My invention further consists in the method or steps hereinafter described, by

iual'ter desrrihed and also fully described in my aforesaid original application and. which I prefer to employ in carrying out the. steps in my method hereimleserilled. for centering or for piercing or penetrating and centering ingots. hloolns. blanks or oiher wnn'lt-pieees and rolling or forming therefrom either dished or undished var wheels. or other circular bodies: for rolling. rerolling. reformon or reworking ear wheels or other circular bodies: and for utilizing ear wheels or other circular objects or reworking the same to form other circular objects therefrom.

K is the herein named tread or face rolling roll which acts against the peripheral face of the work-piece to roll said face to a beaked or rudimentary form or to partly finished form and which, during the rolling process, is moved toward, against or away from the peripheral face of the workpiece: said movements being limited or controlled by adjustable stops provided in the mechanism for causing said movements, as hereinafter described, whereby the radial distance or distances of said roll from the axis of the supported work-piece may be adjusted so as to suit any requirement and whereby said roll may be stopped and retained at any desired radial istance from the axis of the supported work-piece. Said roll is also supported so as to permit latoral movement of the same. The peripheral or rollin face of this roll may also have variousv different shapes, as for instance, in Figs. 1, 4, 7 and 25; or, as for instance K in Figs. 21, 3!), 40, 41, 42 and 46; or. us for instance K in Figs. 26 and 45; or, as for instance, a roll having its rolling face to suit the beaked form K of the peripheral face of a rim portion shown In Fig. 52; or,

Pic'rcers or work-supporting centers and work-supporting heads.

With reference, for instance, to Figs. 1 to 15, 2'2. 23 and 24, illustrating the device I prefer for centering or for piercing or penetrating and centering ingots. blooms, blanks or other work-pieces, for supporting the same, and for putting the work-pieces at their hub or center portion while so supported by said work-supporting centers also into clamped condition laterally or axially between said piercers or work-supporting centers and automatically keeping said hub or center portion in said clamped condition by constant pressure during the rolling and dishing or undishing processes, &c., as here inafter described.

In said figuye's. M. M are the herein named work-supporting heads; although so named they also serve other purposes, as will be observed from the following:

The axles E, E are carried and rotatably supported by said supporting heads M. M.

Each of these axles E. E, has one of said piercers or \\()I'l Sll])])0I'tillI centers at one of its ends. as for instance E or E or E or E" or E or E, &c. These piercers 0r work-supporting centers are interchangeable. Said heads M, M are moved.-with their axles E, E and piercers or work-supporting centers E &c.. in line with the axis of the work-piece by means of the pressure cylinders O and N or by any other equivalent means. tward or away from each other, or they may be moved together in either direction. or one of them may be retained in any position while the other is moved toward or away from the one so retained. or are moved as the case may require. and as and in the manner hereinafter fully described. ()ne of said heads M, M is operatively connected with the piston-rod O of the piston in cylinder 0 and is moved by the pressure in said cylinder 0, and, the other of said heads hi. M. is operatively connected with the piston-rod N of the piston in cylinder N and is moved by the pres sure in said cylinder N. The ends M, l\ of said heads M. M around said axles E, E are formed at an incline with the side of the work-piece, as shown in Figs. 22 and 23, for the purpose hereinafter described.

With reference to Figs. 1, 2 and 3, O is the pressure cylinder for the work-supporting head M located at one side of the Workpiecc: and. N is the pressure cylinder for the worh-suppm-ting head M located at the other side of the work-piece. Cylinder O has a piston with a piston-rod 0 and a piston-rod passing through the cylinder heads 0 and 0" (see Fig. 1) at both ends of cylinder 0. The piston-rod O at its outer end is provided With-a long thread (3 over which is fitted a threaded and adjustable nut O, as shown. This nut O can be adjusted from one end to the other end of said thread 0. At the outer end of said thread is provided a safety stop collar 0 which indicates the limit of adjustment of said nut 0 toward the end of the pistonrod and thereby prevents the piston from coming against the cylinder head 0 The pistonrod O is firmly connected at its outer end with said work-sopporting head M. From the outer end )I' of said head M the piston-rod O is provided with a thread over which is fitted a threaded adjustable nut as shown. This nut O can be adjusted from one end to the other end of said thread. as may be required in adjusting.

the pull-back stroke of the piston with its rods 0; next to said nut O" the pistonrod 0 is also provided with a sleeve or distance piece 0 as shown (the purpose of this piece 0 being described in my said original application). The details and description of the cylinder N and its connecting parts for the head M at the other side of the workpiece. are similar to those described above. and the characters of reference N to N inclusive indicate the corresponding parts for O to O inclusive. The pierccrs or worksupporting centers. with their work-sup'l, porting heads M. M are operated by the pressures in said cylinders O and N actin against the pistons of said piston-rods N", N and O 0 in the manner hereinafter described.

t'enfere'ng 01' piercing or penetrating and centering.

By the words centering. or piercing or penetrating and centering used herein. I mean that. the ingot. bloom. blank or other work-piece is centered. or pierced or penetratcd and centered by the apparatus or mill. by forcing either one or both said piercers or work-supporting centers against or into said workpiece by their pressure means. when the outer portion or periphery of said work-piece is brought coaxial, or approximately coaxial. with the piercers or work-supporting centers by means of said raising. lowering and retaining device, and this herein means said Work-piece is cantered. or pierced or penetrated and centered, because said piercing or penetrating at the same time also centers said work-piece, because. at the beginning of said centering or piercing or penetrating and centering process, the outer portion or periphery of said work-piece is then coaxial. or approximately so. with said piercers or work-supporting centers: that is. said piercers or Work-supporting centers are then in the center, or approximately in the center of the outer portion or periphery of said work-piece. It is, of course, understood that when a.
